Boiko M.V., Bulgarevich S. B., Kogan V.A., Increase of the exploitation properties of the construction steels with the help of modification their surface oxide films on nanolevel.
The molecular coordinative mechanism of iron and its alloys oxide film distraction in the solutions due to ligand substitution in the coordinative polyhedrons of oxide film is proposed. Method of steel oxide film dopping in solutions with the help of transition metal cations is proposed too. It is economic profitable taking into account the big expenditures of the dopping steel production. The method of steel corrosion inhibiting by means of dopping the oxide layers on its surface by nanoparticles of the mixed oxides of the transition metals was found.
Key words: oxide film, ligand substitution, protection from corrosion, nanoparticles of the mixed oxides.
Alexandrov A.A., Tribospectral identification of thermomechanical damages on contact model «a wheel crest - a lateral surface of a wheel»
The tribospectral method is offered for the identification of the thermomechanical damages of pair a wheel crest - a lateral surface of a wheel. Method working off was carried out on the standard device of a friction SMT – 1. Simultaneous measurements of dynamics of the actual area of a contact and amplitude- and phase – frequency characteristics of mechanical stresses and the subsequent the analysis of thermodamages have been spent. Using a method of tribospectral identifications the information channel (a certain frequency range, characteristic for processes of thermodamages) has been defined. Such technique will allow to create further system for the control, monitoring and forecasting of behaviour of frictional contact to the purpose of detection of abnormal processes and the control of presence of the third body in contact.
Keywords: thermomechanical damages, a contact zone, frictional pair, modelling, complex measurements, tribospectral identification, an information channel, the control, monitoring
